Gas exchange through drainage holes
Like some others I have found that I like to set my SH pots in saucers to catch "dribbles" from imperfectly drilled holes. But I ran out of saucers today, and I have an oversupply of slightly strangely shaped plastic Ikea pots (see picture; the SH pot is sitting on the lip of the lower pot). But the construction of the pots is such that it leaves very little clearance for the drainage holes, maybe about 1mm and probably interfering with any gas exchange that might take place through the drainage holes (I have another variety of this pot that makes a tight seal against the holes) What is the general thoughts about blocking these holes? Are the drainage holes important for gas exchange? Or is the air that goes up and down the top of the pot sufficient?
